CVE-2011-2939 2 Dan Kogai, Perl 2 Encode Module, Perl 2023-02-12 5.1 MEDIUM N/A
Off-by-one error in the decode_xs function in Unicode/Unicode.xs in the Encode module before 2.44, as used in Perl before 5.15.6, might allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Unicode string, which triggers a heap-based buffer overflow.
CVE-2009-1884 2 Bzip, Perl 2 Compress-raw-bzip2, Perl 2023-02-12 4.3 MEDIUM N/A
Off-by-one error in the bzinflate function in Bzip2.xs in the Compress-Raw-Bzip2 module before 2.018 for Perl allows context-dependent attackers to cause a denial of service (application hang or crash) via a crafted bzip2 compressed stream that triggers a buffer overflow, a related issue to CVE-2009-1391.
CVE-2020-12723 5 Fedoraproject, Netapp, Opensuse and 2 more 16 Fedora, Oncommand Workflow Automation, Snap Creator Framework and 13 more 2022-05-12 5.0 MEDIUM 7.5 HIGH
regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls.
CVE-2020-10878 5 Fedoraproject, Netapp, Opensuse and 2 more 17 Fedora, Oncommand Workflow Automation, Snap Creator Framework and 14 more 2022-05-12 7.5 HIGH 8.6 HIGH
Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection.
CVE-2020-10543 4 Fedoraproject, Opensuse, Oracle and 1 more 15 Fedora, Leap, Communications Billing And Revenue Management and 12 more 2022-05-12 6.4 MEDIUM 8.2 HIGH
Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow.
CVE-2021-36770 3 Fedoraproject, P5-encode Project, Perl 3 Fedora, P5-encode, Perl 2022-05-03 6.8 MEDIUM 7.8 HIGH
Encode.pm, as distributed in Perl through 5.34.0, allows local users to gain privileges via a Trojan horse Encode::ConfigLocal library (in the current working directory) that preempts dynamic module loading. Exploitation requires an unusual configuration, and certain 2021 versions of Encode.pm (3.05 through 3.11). This issue occurs because the || operator evaluates @INC in a scalar context, and thus @INC has only an integer value.
CVE-2016-6185 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2021-09-17 4.6 MEDIUM 7.8 HIGH
The XSLoader::load method in XSLoader in Perl does not properly locate .so files when called in a string eval, which might allow local users to execute arbitrary code via a Trojan horse library under the current working directory.
CVE-2016-2381 5 Canonical, Debian, Opensuse and 2 more 10 Ubuntu Linux, Debian Linux, Opensuse and 7 more 2020-09-10 5.0 MEDIUM 7.5 HIGH
Perl might allow context-dependent attackers to bypass the taint protection mechanism in a child process via duplicate environment variables in envp.
CVE-2018-6913 3 Canonical, Debian, Perl 3 Ubuntu Linux, Debian Linux, Perl 2020-08-24 7.5 HIGH 9.8 CRITICAL
Heap-based buffer overflow in the pack function in Perl before 5.26.2 allows context-dependent attackers to execute arbitrary code via a large item count.
CVE-2018-6797 4 Canonical, Debian, Perl and 1 more 5 Ubuntu Linux, Debian Linux, Perl and 2 more 2020-08-24 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Perl 5.18 through 5.26. A crafted regular expression can cause a heap-based buffer overflow, with control over the bytes written.
CVE-2018-18311 8 Apple, Canonical, Debian and 5 more 18 Mac Os X, Ubuntu Linux, Debian Linux and 15 more 2020-08-24 7.5 HIGH 9.8 CRITICAL
Perl before 5.26.3 and 5.28.x before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
CVE-2018-12015 6 Apple, Archive\, Canonical and 3 more 9 Mac Os X, \, Ubuntu Linux and 6 more 2020-08-24 6.4 MEDIUM 7.5 HIGH
In Perl through 5.26.2, the Archive::Tar module allows remote attackers to bypass a directory-traversal protection mechanism, and overwrite arbitrary files, via an archive file containing a symlink and a regular file with the same name.
CVE-2017-12837 1 Perl 1 Perl 2020-07-14 5.0 MEDIUM 7.5 HIGH
Heap-based buffer overflow in the S_regatom function in regcomp.c in Perl 5 before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 allows remote attackers to cause a denial of service (out-of-bounds write) via a regular expression with a '\N{}' escape and the case-insensitive modifier.
CVE-2018-18312 5 Canonical, Debian, Netapp and 2 more 8 Ubuntu Linux, Debian Linux, E-series Santricity Os Controller and 5 more 2020-07-14 7.5 HIGH 9.8 CRITICAL
Perl before 5.26.3 and 5.28.0 before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
CVE-2018-6798 4 Canonical, Debian, Perl and 1 more 5 Ubuntu Linux, Debian Linux, Perl and 2 more 2020-07-14 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Perl 5.22 through 5.26. Matching a crafted locale dependent regular expression can cause a heap-based buffer over-read and potentially information disclosure.
CVE-2018-18313 6 Apple, Canonical, Debian and 3 more 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more 2020-07-14 6.4 MEDIUM 9.1 CRITICAL
Perl before 5.26.3 has a buffer over-read via a crafted regular expression that triggers disclosure of sensitive information from process memory.
CVE-2015-8608 1 Perl 1 Perl 2020-07-14 7.5 HIGH 9.8 CRITICAL
The VDir::MapPathA and VDir::MapPathW functions in Perl 5.22 allow remote attackers to cause a denial of service (out-of-bounds read) and possibly execute arbitrary code via a crafted (1) drive letter or (2) pInName argument.
CVE-2017-12883 1 Perl 1 Perl 2020-07-14 6.4 MEDIUM 9.1 CRITICAL
Buffer overflow in the S_grok_bslash_N function in regcomp.c in Perl 5 before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 allows remote attackers to disclose sensitive information or cause a denial of service (application crash) via a crafted regular expression with an invalid '\N{U+...}' escape.
CVE-2017-12814 2 Microsoft, Perl 2 Windows, Perl 2020-07-14 7.5 HIGH 9.8 CRITICAL
Stack-based buffer overflow in the CPerlHost::Add method in win32/perlhost.h in Perl before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 on Windows allows attackers to execute arbitrary code via a long environment variable.
CVE-2018-18314 5 Canonical, Debian, Netapp and 2 more 8 Ubuntu Linux, Debian Linux, E-series Santricity Os Controller and 5 more 2020-07-14 7.5 HIGH 9.8 CRITICAL
Perl before 5.26.3 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
