CVE-2020-10878

Perl before 5.30.3 contains an integer overflow in the regular expression compiler (related to PL_regkind[OP(n)] == NOTHING). A crafted regex can produce malformed bytecode with a possibility of instruction injection, as documented by multiple advisories and CVEs (e.g., CVE-2020-10878). Public re...

CVE-2020-10543

CVE-2020-10543 affects Perl before 5.30.3 on 32-bit platforms, where nested regular expression quantifiers cause a heap-based buffer overflow (integer overflow) in the regex compiler. The connected advisories confirm fixes/updates for Perl (e.g., CloudLinux, AlmaLinux, ALAS2), indicating remediat...

[SECURITY] Fedora 32 Update: perl-5.30.3-453.fc32

Perl is a high-level programming language with roots in C, sed, awk and she ll scripting. Perl is good at handling processes and files, and is especially good at handling text. Perl's hallmarks are practicality and efficiency. While it is used to do a lot of different things, Perl's most common...

Fixed CVE-2020-10543, CVE-2020-10878 and CVE-2020-12723 Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website. Tenable has attempted to automatically clean and format it as much as possible without introducing additional...

Perl buffer overflow vulnerability (CNVD-2020-37944)

Perl is a general-purpose, interpreted, dynamic cross-platform programming language from the Perl community. A buffer overflow vulnerability exists in Perl Core. An attacker could exploit this vulnerability to cause a denial of service and possibly execute code...

Perl Input Validation Error Vulnerability

Perl is a general-purpose, interpreted, dynamic cross-platform programming language from the Perl community. An input validation error vulnerability exists in Perl versions prior to 5.30.3, which stems from the program's failure to properly handle the "PLregkindOPn == NOTHING" case. The...

Fedora 31 : perl-Email-MIME / perl-Email-MIME-ContentType (2020-39d40d9ae9)

This update limits the number of nested MIME parts to 10 by default, to avoid a possible memory exhaustion issue with lots of tiny MIME parts. Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website. Tenable has attempted to...

CVE-2020-12723

regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive Sstudychunk calls. An application written in Perl would only be vulnerable to this flaw if it evaluates regular expressions supplied by the attacker. Evaluating regular expressions in th...
